US Naval War College Review – The geopolitics of the twenty-first century will look very different from that of the twentieth century, but does that mean that the lessons of the latter do not apply to the former? Will competition for oil be eclipsed by that for rare earth metals or lithium, such that the form but not the substance will change? Or does the possibility of achieving self-sufficiency in energy consumption through renewables offer an alternative to interstate resource competition or interdependence? Most importantly, does the challenge of climate change compel Americans to rethink their rivalry with China? Reading “The New Map” will stimulate thinking along these lines, but doing so is only the first step.
